Specification of Letters Patent.

Patented June 26, 1906.

Application filed July 14:, 1905- Serial No. 269,678.

To all whom it may concern:

Be it known that I, HENRY R. WHITE, a citizen of the United States, residing at Brainerd, in the county of Crow Wing and State of Minnesota, have invented certain new and useful Improvements in Flame-Regulators for Lamp-Burners, of which the following is a specification.

My invention relates to lamp-burners, and has for its object the provision of an attachment thereto for the purpose of regulating the amount of flame, and is of especial use where the lamp is used for heating purposes, my invention serving the purpose of a heatregulator. In incubators and brooders, for instance, a lamp is used for maintaining a predetermined temperature in the machine, and while a damper actuated bya thermostat is used for controlling the flow of heat from the lamp, so as to maintain a uniform temperature therein, still when the weather moderates it is often necessary to reduce the amount of flame produced by the burner, so as to secure the most successful operation of the machine, as well as revent unnecessary consumption of fuel. l nder the old practice this reduction of flame area was accomplished by lowering the Wick; but there is always danger of the flame burning out entirely when such a practice is in vogue, thus spoiling the batch or killing the chicks.

My invention provides means for regulating the amount of flame area Without lowering the wick into the wick-tube and it consists of a plate pivotally and slidably mounted on the wick-tube and so arranged that when desired to limit the flame area of the lamp it is adjusted over the wick so as to cover any part of it desired and the flame area accordingly limited to the extent requisite for successful operation of the machine.

My invention will be particularly described hereinafter and the preferred form thereof illustrated in the accompanying drawings, in Wl1l0l1 Figure 1 is aside view of a conventional lamp-burner, showing my invention secured to the wick-tube thereof; Fig. 2, a top plan view of the wick-tube, showing my invention applied thereto, but in position so that the entire flame area of the wick is exposed; Fig. 3, a view similar to Fig. 2, showing my invention in operative positionviz., covering a portion of the .end of the wick. Fig. 4 is a vertical sectional view of a fragment of the wick-tube and of my regulator, and Fig. 5 a view of my regulator detached from the burner and unassembled.

In the drawings similar reference characters indicate corresponding parts throughout the several views.

A represents the wick-tube of a lampburner, and B a plate secured thereto, having its ends C bent to inclose the ends of the tube A to retain the plate in position thereon.

D represents a tubular bearing formed by bending an extension of a portion of the top edge of plate B.

E represents the flame-regulating plate, having depending therefrom flanges F and G. Flange F has an extension and is rolled on itself, as shown at H, to form a journal for plate E, which fits into bearing D, flange F being also slotted for a portion of its length, as shown at I.

In use my invention is attached to the wick-tube, as shown in the drawings, by means of bent portions C of plate B. When the full flame area of the burner is utilized, the device is in the position shown in Fig. 2; but when it is desired to limit the flame area the plate E is adjusted so as to ex ose only a part of the wick, the journal H a mitting of swinging the plate E over the top of the wicktube A, as well as sliding it thereon, so that as much or as little desired of the flame area of the wick is exposed and the amount of heat generated thereby and the consumption of fuel correspondingly limited.

Having thus described my invention, what I claim is 1. In combination with the wick-tube of a lamp-burner, a plate secured thereto and revolubly and shdably mounted thereon to regulate the extent of flame area of the wick, substantially as shown and described.

2. In combination with the wick-tube of a lamp burner, a tubular bearing secured thereto, and a plate havin a journal mounted in said bearing, said p ate being adapted to rotate in said bearing to rest on said Wicktube and to swing clear thereof and also slide on said wick-tube, as and for the purpose described.

3. In combination with the wick-tube of a lamp-burner, a plate secured thereto, a tubular bearing integral with said plate, and a 1 In testimony whereofI heretO my sigplate having a journal adapted to fit into a nature inthe presence of tWb Witnesses.

Said bearing, Said plate adapted to be R rotated in said bearing to rest on said Wicktube and be slid lengthwise of the tube and Witnesses:

also to be swung clear of the top of the Wick- CHARLES, B. WHITE,

tube, as and for the purpose described. ED. MATTSON.
